This may help.
I've also read a paper about thsi based on relationship between characters in certain manga. Unfortunately I forgot the title. All I know is that it's pretty old, not translated, about robots and I think the primary relationship is between parents and their robot daughter.
is the title Dr. Slump? I think I saw some episodes before in Chinese, but I totally forgot about it
edit: Oh wait it is licensed in English O____o;; nevermind it might not be then....
